The paper investigated the application of gravel as partial economic replacement of granite in concrete production. Concrete was produced using granitegravel combination in varying percentages of 9010, 8020, 7030, 6040, 5050, 4060, 3070, 2080 and 1090. Concrete made from 100 granite and 100 gravel served controls while other constituents of concrete were kept constant.
2017-12-12Normal strength concrete made with basalt and gravel gave similar compressive strength while the concrete containing limestone attained higher strength. The effects of content and particle size distribution of coarse aggregate on the compressive strength of concrete have been investigated Meddah, Zitouni, and Belabes 2010.

Comparative Analysis on the Strength of Concrete Made With . nbsp 0183 32 Normal concrete can be produced from different aggregate and it impart different properties to the resulting concrete The most important property of a concrete is its compressive strength For the purpose of this work the two type of coarse aggregate are local gravel and granite The fine aggregate is normal sand bought ...
Although concrete is a noncombustible material, high temperatures such as those experienced during a fire have a negative effect on the mechanical properties. This paper studies the effect of elevated temperatures on the mechanical properties of limestone, quartzite and granite concrete. Samples from three different concrete mixes with limestone, quartzite and granite coarse aggregates were ...
